A universal translator is a device common to many science fiction works, especially on television. First described in Murray Leinster's 1945 novella "First Contact", the translator's purpose is to offer an instant translation of any language. Technology companies are striving to develop a practical "universal" translator for common use.
As a convention, it is used to remove the problem of translating between alien languages, unless that problem is essential to the plot. To translate a new language in every episode when a new species or culture is encountered would consume time (especially when most of these shows have a half-hour or one-hour format) normally allotted for plot development and would potentially, across many episodes, become repetitive to the point of annoyance. Occasionally, alien races are able to extrapolate the rules of English from very little speech and then immediately be fluent in it, making the translator unnecessary.
While a universal translator seems unlikely, due to the apparent need for telepathy, scientists continue to work towards similar real-world technologies involving small numbers of known languages. See machine translation and speech recognition for discussions of real-world natural language processing technologies.

Famous quotes containing the word universal:
“The earliest instinct of the child, and the ripest experience of age, unite in affirming simplicity to be the truest and profoundest part for man. Likewise this simplicity is so universal and all-containing as a rule for human life, that the subtlest bad man, and the purest good man, as well as the profoundest wise man, do all alike present it on that side which they socially turn to the inquisitive and unscrupulous world.”
—Herman Melville (18191891)
